Yini Okufanele Icatshangelwe Ngaphambi Kokuthenga I-PV DC Nqamula Iswishi?

Ekufakweni kwe-PV, iIswishi yokunqamula i-DCkufana ne-airbag emotweni.Izinga le-IEC 60364-7-712 lidinga ukusetshenziswa kwe-PV DC yokunqamula amaswishi phakathi kohlu lwe-PV nesiguquli.Amaswishi okunqamula i-Slocable DC aklanyelwe ngokuqondile ukunqamula iziguquli ze-DC/AC ezinhlelweni zamaphaneli elanga.Sinikeza amaswishi e-PV yokunqamula ama-voltage afika ku-1500 V DC.Angasetshenziselwa ukwakha amaphuzu okushintsha azimele njengoba kudingwa i-VDE 6012, isibonelo, ukuvumela ukunqanyulwa okuphephile kwama-inverters angasebenzi.Wonke ama-switch switch e-DC ashintsha isixhumi ezigxotsheni ezimbili futhi afanele amasistimu avubukuliwe.

Izindlu zeswishi yokunqamula i-PV isilungele ukufakwa futhi inikeza ukusebenza kwamanje okungu-30 A ku-1000 V/1500 V DC.Itholakala ngezintambo ezimbili nezine kanye nezinhlobo ezimbili zokuxhuma ezivame kakhulu zokuxhuma.I-MC4 noma izindlala zekhebula le-metric zivumela ukuhlanganiswa okushelelayo emicabangweni ehlukene yesistimu.Indawo evalekile yokunqamula ukushintsha kwe-DC inesigaba sokuvikela i-IP66 futhi ifaneleka kahle ukufakwa ngaphandle.Umsebenzi wokukhiya uhlinzeka ngokuvikeleka ngesikhathi sesevisi nokulungiswa.Isici sesinxephezelo sokucindezela sivimbela ukufingqa ekuqoqweni futhi ngaleyo ndlela kuvimbele ukwehluleka ngenxa yombani.

Yini Okufanele Icatshangelwe Ngaphambi Kokuthenga I-PV Nqamula Iswishi?

1. Hlobo luni oludingayo?

Udinga ukucabangela uhlobo lweswishi yokunqamula i-PV edingekayo, isibonelo ukuze uqonde izidingo zakho zamandla.I-Slocable inokushintsha kokunqamula kusuka ku-DC 1000V kuya ku-1500V.Uma ufuna isixazululo esenziwe ngokwezifiso, singase futhi sinikeze amaswishi okunqamula i-PV ku-600V, 800V, 1000V, 1200V noma 1500V.

2. Amandla kagesi kanye namanje

Uma ufuna ukufaka iswishi yokunqamula i-DC, kufanele usayizise abathintwayo bayo ukuze uqinisekise ukuthi ikwazi ukuthwala amandla adluliswa ngegridi yayo.

Uma udinga ama-curse aphezulu, uzodinga abathintwayo abakhulu ukuze uwasekele ukuze ugweme ukushisisa ngokweqile kwesistimu kagesi.Amaswishi ethu okunqamula i-Slocable PV asukela ku-1000V, 1200V kuya ku-1500 futhi akalwe ku-32A naku-55A.

3. Izitifiketi ze-IEC ne-AS

Okunye okumele kubhekwe wukwazi izitifiketi ze-IEC ne-AS.Uma umakhi weswishi yokunqamula i-DC enalezi zitifiketi, kusho ukuthi inkampani ilandela imihlahlandlela yamazwe ngamazwe lapho ikhiqiza i-PV DC inqamula imikhiqizo yokushintsha.

Isibonelo, engxenyeni yokuqala ye-EIC 60204-1:2016, umkhiqizi kudingeka ukuthi anikeze amaswishi okunqamula aqhutshwa mathupha kumthombo wamandla ngamunye oyinhloko ofakwayo kanye nemingcele ethile yedizayini.

4. Indlela yokufaka

Uzodinga futhi ukucabangela indawo oyincamelayo yokukhweza iswishi yokunqamula i-DC kanye nesitayela sokukhweza esilungele uhlelo lwakho lokusebenza.Isitayela esivame kakhulu intaba enezimbobo ezine, eyakhiwe ngephethini yesikwele enezimbobo ezine-screw ekhoneni ngalinye.Lesi sitayela sifanelekile uma uhlose ukukhweza iswishi endaweni eyisicaba, njengoba sivumela iswishi ukuthi iguqe ngangokunokwenzeka.

Izici ze-Slocable PV DC disconnect switch:

1. Okuxhunyanwa nabo emaphethelweni ommese okuthembeke kakhulu kanye negumbi lokupholisa le-arc ende liqinisekisa ukuhlukaniswa okuphephile kwe-DC voltage.
2. Khulisa ukuphepha ngesici se-Slocable esithi “Ukukhiya Kokuphepha” esinelungelo lobunikazi.
3. Uchungechunge lwe-Slocable PV yokunqamula ukuxhuma luyatholakala ezinguqulweni zezigxobo ezingu-2 kuya kweziyisi-8 futhi ezinhlobonhlobo zokukhweza nokubamba kwezinhlelo zokusebenza eziningi zokufakwa kwe-OEM noma inkambu.

Lezi zinguquko ze-PV zihlolwe abahloli futhi ziyi-UL508i, TUV (60947-1 & 60947-3), CE kanye ne-CCC eqinisekisiwe.

I-Slocable iphinde inikeze ezinye izesekeli ze-PV zelanga, okuhlanganisa izixhumi zeSolar MC4, izibambi zefuse ze-MC4, amabhokisi okuhlanganisa ama-photovoltaic kanye nabavikeli be-DC.
